BELT-HOOK PLIERS AND PUNCH.

Specification of Letters Patent. No. 25,567, dated September 27, 1859.

To all 'whom it may concern:

Be it known that I, N. EHALE, of Nashua, Hillsboro county, State of New Hampshire, have invented an Improvement in Combined Belt-Hook Pliers and Punches; and I do hereby declare that the following is a full and exact description of its construction and operation, reference being had to the accompanying drawings, and to the letters of reference marked thereon, so as to enable others skilled in the art to make and use my device.

Figure 1 of the accompanying drawings represents a section through the tool; Fig. 2, a perspective view of the same; Fig. 3, the two ends of a belt fastened together by hooks, (top view Fig. 4, one of these hooks, (side view;)` Fig. 5, a section through the ends of the tool with a hook between them; and Fig. 6, a similar section with the hook and both ends of the belt between the pliers.

The object of my tool is to facilitate the use of hooks, such as designated by the letter Q, in Figs. 3, 4, 5, and (3, for the purpose of fastening together the two ends of belts used for driving machinery.

The various operations, to the performance of which this tool is adapted, consists in punching holes through the ends of the belt for the insertion of the hooks, bending and compressing the ends of the hooks after they have been inserted, and of twisting the piece of leather from between the ends of the hooks after it has been cut from one end of the belt when it is desired to shorten the belt and of then unbending or straightening out the hook as shown in Fig. 5, whereby the same hooks can be used over and over again.

A, B, are the handles of the pliers held apart by means of a spring C, and pivoted together at D. The front end of the jaw F, which extends from the handle A, is provided with a roughened surface O. The central part of the aw F, behind the surface O, is hollow as seen at P, and contains the punch J, pivoted at L, and held in place by means of a spring N, which is also arranged in said hollow or recess P. The front end of the jaw E, extending from handle B, is of a triangular section as seen at G; behind G, there is a roughened surface H, and behind the latter a smooth surface I, of soft metal.

When the tool is to be employed for punching the holes for the insertion of the belthooks, thepunch J, is raised from the recess P, into the vertical position drawn in red in Fig. 1, the leather is inserted between the two jaws E, F, and the handles are then compressed when the punch J, will cut through the leather against the soft metal surface I. Then the holes have been out through the belt ends, t-he hooks are inserted into the holes, the punch is turned back into the recess P, (as represented by black lines in Fig. 1,) and the roughened surfaces H, O, are brought over the ends of the hooks and are compressed by means of operating the handles, until the hook ends are turned down so as to firmly grasp the leather. A hook Q, is represented in Fig. 6, with one end T, turned down upon the leather R, and with the other end T, in the process of being turned down as described. Then it is desired to tighten the belt one end is cut off by cutting through the holes close to the hooks. The piece of leather thus cut ofi' is then taken hold of between the jaw ends of the pliers and is twisted out. The edge of the triangular or wedge shaped point G, is then inserted in the open end of the hook and the hook end straightened out as seen in Fig. 5. Then all the hook ends have been thus straightened out, they are inserted into the new holes punched into the belt as above described, and the hook ends are again bent down and tightened between the surfaces H, O. The hook ends can be pressed through the holes after they have been punched, by placing the surface O, upon the upper side of the hook and the edge G, against the under surface of the belt close to the hole and then compressing the handles.

It will be seen that the punch when turned down into the recess P, of the shank, is entirely out of the way and does not at all interfere with the use of the pliers for the purpose of straightening out and bending down of the hooks, &c. as above set forth.

Having described my invention what I claim as new and desire to secure by Letters Patent is 1. The combination of the roughened surfaces O, and H, with the triangular wedge end G, arranged in relation to each other substantially as and for the purposes set forth.

2. The combination of the jaws E, F, with the punch J, roughened surfaces O, H, and wedge end G, the whole being constructed and arranged as and for the purposes set forth.
